What kind of Worms in feces?

[Steph E Caldwell]

Cheif/TeeCee has worms in his feces, lots and lots of them. They're 
about 1/4 - 1/2" logn and are swimming around in his diarhea. I'm giong 
to call my vet tomorrow, but any idea what htis might be?

When we did bloodwork this week on his annual checkup his liver enzymes 
were a tad high... But, otherwise he got a clean bill of health from teh 
vet.
